CAR-ROOF.

essaies.

roofs intended primarily for freight cars,v

but it' is applicable to Vother kinds of roofs.

. The objects of the invention are simplicity,

strength, durability, and tightness against leaks. vA further object ofthe invention is the prevention ofcon'densation of moisture or sweatingon the under sides of the roof plates. l

This invention consists in the shape and arrangement of the carlines androof plates and manner of securing them together.l The invention alsoconsists in arranging a wood lining beneath the roof plates, and in themanner of assembling and retaining the lining in place. Theinventionalso consists in .the running board supports and manner of securing themto the roof.

Furt

in connection with the following description of the car roof shown inthe accompanying A drawings, and what the invention consists Ain is moreparticularly dened in the ap pended claims.

In the drawings, in which the same reference characters designate thesame parts in the several views,

the eaves portion of the roof on `the line 2-2 in Fig. 1; and

Fig. 7 is -a longitudinal section throughl the end of the car at theridge, on the line 7 7 in Fig. 1.

The roof shown in the drawings is applied to a car having Z bar sideplates 10 and a pressed metal-end plate 11; but the ii/ivention isapplicable to cars having w/ood side and end plates. rThe carlines 12ersof pressed steel, channel shape in crosssecn tion, with the top edgesof'their side walls. flanged outward for supporting the roof.

beneath the roof plates. The ends of the carline flangesare bent downand hooked over and riveted to the inner flanges of the side plates. Endbrackets 16 of pressed steel conforming t the shape of the under side ofthe carline at its ends are riveted to the side of the carline, and tothe inner sides lof the side plates.

The side margins of the' roof plates are lapped over the carliiies, andare secured together and to the carline-langes by two rows of rivets 17.The rivets of each row pass through both roof plates and one of the sideiianges of the supporting /carline between the trough portion thereofandthe depressed edge 14- which forms a seat for the lining boards. Thelapping portions of the roof plates and the carline together constitutea plate-carline of box-like shape having great vertical and lateralstiffness. The roof plates are spaced above the top edges of the sidepiates, and their eaves ends 18 are flanged downloyer the outer sides ofthe side plates and are spaced a slight distance away from them. Thedownturned eaves anges 18 of the roof sheets are secured to the sideplates at their corners by rivets 19 which go through the ends of thecarlines The running boards 20 are bolted to angle iron cross ieces 21which are supported at their ends y sheet metal brackets 22 which restupon;l

the roof sheets over the carlines on each side of the ridge and areriveted'to the carline flanges.

The invention is not restricted to the details ol construction shown inthe drawings. l claim the following as my invention: v

1. A metal car roof comprisingtrough shape carlines having outwardlyprojecting flanges along the tops of their side walls, roof platessupported on said carline flanges with their side margins lapping eachother over the troughs of the carlines, and means for rigidly securingsaid lapping margins of said roof plates and said carline anges togetheron both sides of the troughs to form a hollow plate-cardine.

2. A car roof comprising trough shape .carlines having outwardlyprojecting flanges along the tops of their side walls, the side edges ofsaid flanges being depressed to form supports for lining boards, roofplates supported onvthe top portions of said carline flanges with theirside margins lapping each other over the troughs' of the carlines,lining boards arrangedbetween said carlines with their ends between saidroof plates and the depressed edges of said carlinel langes; and meansfor rigidly securing said lapping margins of said roof plates and saidcarline flanges together on both sides Y`of the troughs to secure saidlining hoatrds in place.

insens 3. A metal car roof comprising side plates channel carlineshaving outwardly projecting flanges along the tops of their side walls,

the ends of said carlines being bent' down f85 over the side plates,roof plates supported on said carlines with their side margins eX-tending across the channels and each riveted to both flanges `of eachcarline, said roof plates having their eaves ends turned down 10 'overthe side plates, and means for rigidly f securing said eaves ends ofsaid roof plates and said carline flanges to said side plates. 4. Ametal lcar roof comprising side plates channel carlines having outwardly45 projecting flanges along the tops of their side Walls, the ends -ofsaid carlines being `bent down over the side plates, roof plates ,1" vsupported on said carlines with, their side; margins extending acrossthe channels and'p each riveted to both llanges of each carline, x saidroof plates having their eaves ends i.
